MLS Grid Web API v2 is published by [MLS Grid](https://apis.io/providers/mls-grid/) on the [APIs.io](https://apis.io/) network. Tagged areas include Real-Estate, MLS, RESO, OData, and Property Listings. The published artifact set on APIs.io includes API documentation, an API reference, a getting-started guide, rate-limit docs, authentication docs, and a support channel.

MLS Grid's RESO Web API — a replication-oriented OData v4 surface over listing data normalized to the RESO Data Dictionary and pooled from the participating MLSs. Documented entity sets are Property, Member, Office, OpenHouse and Lookup, with Media, Rooms and UnitTypes available through $expand (and Media standalone where the originating MLS permits). Replication is driven by $filter on OriginatingSystemName plus ModificationTimestamp, paged with @odata.nextLink. Authentication is a long-lived OAuth 2.0 bearer token issued through the MLS Grid web application after a subscription, a licensee and MLS approval are in place; the service requires an Accept-Encoding header containing gzip on every request. Documented rate limits are 2 requests/second, 7,200 requests/hour, 40,000 requests/24 hours and 4 GB/hour, enforced with HTTP 429 and token suspension. Probed anonymously on 2026-07-26: the service root, /Property and $metadata all returned HTTP 401, so no machine-readable contract could be downloaded.
